The present disclosure relates to a display device. A downward-bending portion is formed on an end of an inner plate arranged on the inner surface of a back cover, which is a back support structure of the display device, such that the outer surface of the downward-bending portion contacts the inner surface of the back cover, thereby improving the rigidity and heat-radiating performance of the inner plate, and guaranteeing that the elastic force from the downward-bending portion prevents the display panel from being damaged by cracks. Furthermore, an inward-bending portion is formed on the front end of the vertical extension portion of the back cover, thereby improving the rigidity of the back cover, and guaranteeing that elastic deformation of the inward-bending portion protects the display device from lateral impacts.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A display device comprising: a display panel having a rear side and a plurality of lateral sides; a back cover comprising a horizontal portion supporting the rear side of the display panel and a vertical extension portion extending vertically from an end of the horizontal portion, so as to cover the lateral sides of the display panel; and an inner plate disposed between the display panel and the back cover and comprising a first horizontal portion having an inner surface attached to an inner surface of the horizontal portion of the back cover through an adhesive member, a downward-bending portion bent toward the back cover and extended from a periphery of the first horizontal portion of the inner plate, and a second horizontal portion extended from the downward-bending portion, wherein the second horizontal portion has an outer surface directly contacting the inner surface of the horizontal portion of the back cover without an additional adhesive member.
2. The display device of claim 1 , wherein the back cover comprises an inward-bending portion arranged at an end of the vertical extension portion of the back cover so as to be bent toward at least one of the lateral sides of the display panel.
3. The display device of claim 2 , further comprising a first gap for elastic deformation of the inward-bending portion provided between the vertical extension portion of the back cover and the inward-bending portion of the back cover.
4. The display device of claim 2 , further comprising a second gap for elastic deformation of the downward-bending portion provided between the first and second horizontal portions of the inner plate and the downward-bending portion of the inner plate.
5. The display device of claim 1 , wherein the downward-bending portion of the inner plate is configured to dissipate heat generated from the display panel through the back cover contacting the downward-bending portion of the inner plate.
6. The display device of claim 5 , wherein the downward-bending portion of the inner plate has a double-folded structure comprising a primary folded portion that is primarily folded upward from the second horizontal portion of the inner plate and a secondary folded portion that is folded downward from an end of the primary folded portion.
7. The display device of claim 1 , wherein the display panel includes an organic light-emitting display panel comprising a light-emitting layer comprising a substrate, multiple thin-film transistors on the substrate, and an organic light-emitting element layer emitting light between two electrode layers arranged on one side of the thin-film transistors, and an encapsulation layer arranged on one side of the light-emitting layer.
8. The display device of claim 7 , wherein the organic light-emitting display panel includes a bottom-emission type such that light from the organic light-emitting element layer is discharged through the substrate.
9. The display device of claim 8 , wherein, when a surface through which light from the organic light-emitting display panel is discharged is defined as an image display surface, the light-emitting layer and the encapsulation layer are successively laminated under the image display surface, the light-emitting layer has the substrate, the thin-film transistors, and the organic light-emitting element layer successively arranged under the image display surface, and a polarizing layer is arranged on the upper portion of the substrate.
10. The display device of claim 9 , wherein the organic light-emitting element layer includes a white organic light-emitting element layer emitting white light, and the light-emitting layer comprises a color filter layer arranged on the white organic light-emitting element layer.
11. A display device, comprising: a display panel having a rear side and a plurality of lateral sides; a back cover comprising a first horizontal portion, a first vertical portion and a first bending portion, wherein the first horizontal portion supports the rear side of the display panel and the first vertical extension portion is vertically extended from an end of the first horizontal portion to cover the lateral sides of the display panel, and the first bending portion is extended from the first vertical portion; and an inner plate disposed between the display panel and the back cover and comprising a second horizontal portion, a third horizontal portion and a second bending portion, wherein the second horizontal portion has an inner surface attached to an inner surface of the first horizontal portion and the second bending portion bent toward the back cover and extended from a periphery of the second horizontal portion, and the third horizontal portion extended from the second bending portion, and wherein the third horizontal portion has an outer surface directly contacting the inner surface of the first horizontal portion without an additional adhesive member.
12. The display device of claim 11 , further comprising a first gap for providing a first elastic deformation of the first bending portion located between the first vertical extension portion and the first bending portion.
13. The display device of claim 11 , further comprising a second gap for providing a second elastic deformation of the second bending portion located between the second horizontal portion and the second bending portion.
14. The display device of claim 11 , further comprising a first adhesive member disposed between the display panel and the back cover.
15. The display device of claim 11 , wherein the first horizontal portion and the second horizontal portion are attached with each other through a second adhesive member.
16. The display device of claim 15 , wherein the second adhesive member includes a double sided tape.
17. The display device of claim 11 , wherein the second bending portion has a double-folded structure comprising a primary folded portion primarily folded upward from the second horizontal portion and a secondary folded portion folded downward from an end of the primary folded portion.
18. The display device of claim 11 , wherein the first vertical portion has a length greater than that of the first bending portion.
19. The display device of claim 11 , wherein the display panel includes an organic light-emitting display panel comprising a light-emitting layer comprising a substrate, multiple thin-film transistors formed on the substrate, and an organic light-emitting element layer emitting light between two electrode layers arranged on one side of the thin-film transistors, and an encapsulation layer arranged on one side of the light-emitting layer.
20. The display device of claim 19 , wherein the organic light-emitting display panel includes a bottom-emission type such that light from the organic light-emitting element layer is discharged through the substrate.
